More ikvmc testing revealed a couple of IKVM.Reflection.Emit bugs and also some bugs that have been lurking in ikvmc for a long time, that only show up under fairly uncommon scenarios when lots of dependencies are missing (and hence the resulting assembly has little chance of working anyway). The fixes are small and relatively low risk, but I'm not sure whether it is worthwhile to back port them to 0.36 and 0.38. Feedback on this is appreciated.

Changes:

Added support for SpecialNameAttribute and TypeForwardedToAttribute pseudo custom attributes to IKVM.Reflection.Emit.
